That was the server address given when I set it up, however:

bmx:~/.getmail{19} % host imap.mail.yahoo.com
imap.mail.yahoo.com is an alias for sky.imap.mail.yahoo.com.
sky.imap.mail.yahoo.com is an alias for internal.imap.mail.g03.yahoodns.net.
internal.imap.mail.g03.yahoodns.net has address 216.155.194.49
internal.imap.mail.g03.yahoodns.net has address 98.137.159.41

The current address given is imap.mail.att.net:

bmx:~/.getmail{20} % host imap.mail.att.net
imap.mail.att.net is an alias for imap-att.mail.yahoo.com.
imap-att.mail.yahoo.com is an alias for sky.imap.mail.yahoo.com.
sky.imap.mail.yahoo.com is an alias for internal.imap.mail.g03.yahoodns.net.
internal.imap.mail.g03.yahoodns.net has address 98.137.159.41
internal.imap.mail.g03.yahoodns.net has address 216.155.194.49

So it turns out to be the same.

As it happens, using the SELECT command merely changes EXAMINE to
SELECT in the error message. 

Apparently AT&T just implemented a "security upgrade" which requires
replacing the password with a "secure mail key". After I did that,
nothing  changed. Apparently they haven't told the IMAP servers about
it. However, the POP3 servers seem to like it, so changing to
SimplePOP3SSLRetriever works around the problem for now.

Thanks for your help, not to mention getmail itself!
